Application filed March 30, 1906- Serial N0- 308,970.

To all whom it may concern.-

Be it known that I, JOHN WILLIAM Er.- LIOTT, a citizen of the United States, residing at Graham,,in the county of Muhlenberg, and State of Kentucky, have invented a new and useful Cultivator, of which the following is a specification.

This invention relates to cultivators; and it has particular reference to that class of cultivators which are provided with disks and also with shovels for the purpose of cultivating the soil, said disks and shovels being so arranged that they may be used simultaneously or independently of each other, as may be preferred.

The invention has for its object to provide improved means for connecting the cultivating implements with the frame.

A further object is to provide improved means for supporting and adjusting the cultivating implements.

Further objects are to improve and simplify the general construction and operation of the class of devices to which the invention belongs.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly ointed out in theclaims.

In t e accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modifications within the scope of the invention may be made when desired.

In the drawings, Figure 1 is a top plan view of a cultivator constructed in accordance with the principles of the invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a rear elevation. Fig. 4 is a perspective detail View showing the manner of connecting one of the cultivator-gangs with thev frame. Fig. 5 is a sectional detail view of one of the disks and related parts, illustrating the manner of mounting the disk. Fig. 6 is a detail side view of a portion of the device.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The frame of the improved cultivator includes the axle-1, having a centrally-disposed of its ends with a 4 are secured upon.

bars support a cross-bar 5, having depending links 6, provided with the axle 1.

The rear ends of the tongue-bars 4 4 are connected by a cross-bar 9, supporting the drivers seat 10 and having terminal ,sup-

fporting-hooks 1 1 for the cultivator-gangs .12,

which latter are rovided at their frontends with downturne hooks 13, adapted for detachable engagement with apertures :14 in, the axle, the latter being provided near each plurality of such apertures,

with which the cultivator-gangs may be detachably engaged, thus enabling said gangs to be convenientlyspaced at various distances apart suitableto the formed. When the cultivator-gangs are not to be actively employed, theymay be .su ported upon the hooks 11,at the ends oft e cross-bar 9, as will be readily understood.

A yoke 15, which is fitted in the axle-arch 2, is pivotally connected with the side members of said arch, and a link 16 connects said yoke with the lower end of a lever 17, which is pivoted upon one of the tongue-bars 4. The upper end of said lever has a pivoted handle-bar 18, which is provided in its lower edge withnotches 19, adapted for engagement with a bifurcated supporting member 20, which is secured upon the tongue-bar 4 in rear of the lever 17. Said lever may be conveniently manipulated by the handle 18 in such a manner as to rock or oscillate the yoke 15, which latter may be secured at various adjustments by placing the notchedhandle 18 in engagement with the member 20.

The limbs of the yoke 15 have terminal spindles 21, engaging sockets 22 at the upper end of the bifurcated disk-carrying members 23, the sockets 22 having set-screws 24, whereby they may be secured adjustably upon the spindles. Disks 25 of the ordinary concavo-conveX pattern are supported for rotation by the bifurcated members 23, which latter are curved to correspond with the curvature of the disks. As will be'readily seen, by adjusting the yoke 15 the disks may be set to operate in the. ground at various with terminal eyes 7,. through which are guided'the draft-links 8, the rear ends of which are suitably connected work that is to be'per depths, and by adjusting the disk-carrying members upon their respective spindles the disks may be adjusted to operate at various angles and in such a manner as to move the dirt either in an inward or an outward direction toward or from the plants that are being operated upon.

As will be seen from the foregoing description, taken in connection with the drawings hereto annexed, this improved cultivating implement is so constructed and arranged that the disks and the shovel-carrying gangs may be used simultaneously or independently of each other, as may be preferred and as may be indicated bythe work that is to be performed. When the disks and the shovels are used simultaneously, the former may be regarded as operating in the nature of fenders to prevent clods of dirt, stones, and the like from being thrown in the direction of the plants that are being operated upon, said plants being thus protected from injury.

The cultivator-gangs may be very easily and it is intended.

Having thus described the invention, what is claimed is 1. In a cultivator, a wheel-carrying axle having a central arch, forwardly-converging tongue-bars secured upon the sides of the arc%, and a disk-carrying yoke pivoted in the arc 2. In a cultivator, a wheel-supported axle having a central arch, a yoke pivotedin said arch, means for adjusting the yoke and for securing it at various adjustments, and earthengaging disks carried by the limbs of the yoke. 3. In a cultivator, a wheel-supported axle having an arch, a yoke pivoted in the arch and having terminal spindles, disk-carrying members adjustably mounted upon the spindles, and means for adjusting the yoke and for securing it at various adjustments.

4. In a cultivator, an axle having an arch, a yoke pivoted in the arch and having terminal spindles, and bifurcated disk-carrying members having spindle-engaging sockets and securing means.

5. In a cultivator, an axle having an arch, forwardly-converging tongue-bars secured upon the arch, a yoke pivoted in the arch, disk-carrying members connected adjustably with the limbs of the yoke, a lever pivoted upon one of'the tongue-bars, a link connecting one end of said lever with the yoke, a notched handle member connected ivotally with the other end of the lever, an a bifurcated guide and stop member for the handle.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
